The Museum possesses one specimen of each sex. 



This is closely related to E. quadrinotatus Gerst. and 

 E. insignis Gorh., but differs from both in having the anterior 

 yellow patch of the elytron placed at a distance from the 

 front margin and not including the humeral callus. The 

 fl9,ttened margins are a little less wide in the anterior 

 part than, in the former, the hind angles of the thorax 

 are much more produced and acute in the male, and the 

 front tibia in that sex has the tooth stouter, placed nearer 

 the middle and less obhque. The club of the antenna is 

 rather shorter and broader in both sexes. 



In the female the short discoidal carina at the base of 

 each elytron is very distinctive.

 Museum collection and a female in the Cambridge University 

 Museum. 



It is a species related to E. guerini and E. fryanus, but 

 of a rather narrow and regularly oval shape, with the
